Ryzen 9 5950X manually overclocked to 4.45 GHz all-core at 1.312 V on a Gigabyte B550 Aorus Master in a Fractal Design Meshify 2 case with four 140 mm case fans. Cinebench R23 looped for 30 minutes, steady-state CPU temperature at the end. Ambient is held at 22 to 24 C. The review calls the numbers delta temperature, stored as the rise over ambient. At 100 percent fan speed (1850 RPM) the noise was 42 dBA and the delta 68 C. Set to 40 dBA, which took a 90 percent duty cycle at about 1750 RPM, the delta was 69 C. CPU power and the paste are not stated. The noise measurement distance is not stated.8Reviewgamersnexus.net/coolers/best-cheap-cpu-coolers-benchmarked-deepcool-ak400-reviewRead 16 October 2026Gamers Nexus, review of 3 July 2022, updated 11 March 2024. The 68 W test is an overclocked Ryzen 5 3600 on an MSI MEG X570 Ace, using the cooler's included fan and the Gamers Nexus standardized method. At a normalized 35 dBA (fan at 80 percent) the CPU ran 39 C over ambient. At 100 percent fan speed it ran 38 C over ambient at 39 dBA. The review's 123 W results (59 C and 58 C over ambient) are not stored because the text does not name the CPU used. Ambient and the paste are not stated in the review text.
